### Synchronous Wrapper for Async Call (Task.Run)

Source: https://github.com/duosecurity/duo_universal_csharp/blob/main/DuoUniversal.Example/README.md

This approach wraps an asynchronous Duo client call within Task.Run to be used in a synchronous ASP.NET web application context. It's a reported working solution by users.

```csharp
var token = Task.Run(async () => { return await duoClient.ExchangeAuthorizationCodeFor2faResult(context.Request["code"], username); }).Result;
```

--------------------------------

### Synchronous Wrapper for Async Call (GetAwaiter().GetResult())

Source: https://github.com/duosecurity/duo_universal_csharp/blob/main/DuoUniversal.Example/README.md

This method uses GetAwaiter().GetResult() to synchronously execute an asynchronous Duo client method. This approach has been used internally by Duo for their products.

```csharp
var _idToken = duoClient.ExchangeAuthorizationCodeFor2faResult(duoCode, username).GetAwaiter().GetResult();
```
